When setting a fence post in concrete, how should the top surface be finished?

• A. light broom finish
• B. sloped toward the post
• C. levelled off
• D. sloped away from the post

Answer: (D)

Water drainage around a fence post is the key idea here. Finish the top of the concrete so it slopes away from the post to shed water and prevent moisture from pooling at the base or against the wood. A flat or level top can trap water, increasing the risk of rot and deterioration of the post and footing. Sloping toward the post would direct water into the wood and around the base, accelerating decay. A light broom finish isn’t focused on drainage, and while a level surface might seem tidy, it fails to direct water away.
